System and method for managing multiple connections

A data processing device includes an internal volume that is electromagnetic interference (EMI) isolated and a communication system, disposed in the internal volume, that: determines a first EMI state of at least one device of devices disposed in the internal volume; makes a determination that the first EMI state is an EMI emitting state; and disables communications by the communication system using a high-speed connection while allowing the communications using a low-speed connection.

Panel for reflective broadband electromagnetic shielding

A panel for an electromagnetic shield includes a light-weight, porous, electrically-conductive core layer of metallic foam having generally parallel opposed surfaces and a face sheet having rigidity properties superior to the rigidity properties of the core layer laminated to a surface of the core layer. Alternatively, a panel for a broadband electromagnetic shield includes a composite fiber-reinforced core having opposed surfaces and a layered electrically-conductive composite cover disposed on a surface of the core. The cover includes a first stratum of porous metal exhibiting pronounced low-frequency electromagnetic shielding properties and a second stratum of electrically-conductive elements exhibiting pronounced high-frequency electromagnetic shielding properties secured in an overlapping electrically-continuous relationship to the first stratum, the first stratum being a metallic lattice, and the electrically-conductive elements being a non-woven veil of electrically-nonconductive metal-coated fibers.

Magnetic core fixing structure

An aligned state of core sections is reliably maintained. A fixing structure for a cylindrical magnetic core including an insertion hole into which an electric wire is inserted with a plurality of core sections, which are divided in a circumferential direction, being coaxially aligned with each other, includes a clamping band to be wound around outer circumferential faces of the core sections to tighten the core sections. The magnetic core is accommodated in a holder, and the holder has a holder-side locking-receiving portion at which a remaining portion of the clamping band is locked. Meanwhile, an electric wire fixing portion that is fixed to the electric wire, which passes through the magnetic core, is formed in the holder.

Heat sinks containing polymeric protrusions on a base and optionally further including a foil or tape, as well as methods of making and using thereof, are described herein.

Cooling structures having shielding for electromagnetic inteference

The cooling system includes a series of cooling channels arranged to provide convective cooling, with inserts for shielding electromagnetic interference (EMI) that is propagated by the waveguide nature of the cooling channels. Due to the relatively open nature, the cooling channels can serve to propagate EMI energy. The inserts mitigate the EMI exiting via these channels by attenuating or blocking the EMI. The inserts are shaped to block particular frequencies of EMI. The inserts may include thin sheet metal contoured to a half-wave profile, arranged along each cooling channel.
